Comyc Hardware

Since June 1999 the Comyc Hardware consists of two parts:

  1. a Pentium-III part (since June 1999) and
  2. a Pentium-Pro part (since December 1997).

1. Comyc Pentium-III Part

The hardware was assembled by ICT GmbH and delivered by Siemens AG.

There are 4 modules each consisting of 2 nodes, which are equiped with the following
  • Siemens D1031 Dual Slot1 PCI-Motherboards, 100 MHz system bus, with onboard EIDE Controller
  • 2 Intel Pentium-III 450 MHz, 512 KB L2-Cache
  • 512 MB RAM main memory (PC-100, ECC, 4*128MB DIMM)
  • PCI 2MB graphic card
  • 2 PCI FastEthernet cards (3COM 3C905B), one with Netboot-PROM
  • 19"-industry PC case, shared by 2 nodes
  • 6.3 GB EIDE hard disk
  • 3.5" floppy disc drive
  • PCI SCSI Controler (NCR 53c895)
The modules are located within a 19"-industry case.

1.1 FastEthernet

The network between the nodes consists of custom FastEthernet parts, which are connected by a switch. The switch is a 3COM SuperStack II-3300 with 24 ports (10/100 BaseTX auto). 16 ports are used for the connection to the 8 nodes, 2 ports are used for the connection to the NFS file server and the Pentium-Pro part of Comyc.

 

2. Comyc Pentium-Pro Part

The hardware was assembled and delivered by Parsytec GmbH.

There are 8 modules, which are equiped with the following
  • Tyan Dual PentiumPro PCI-Motherboards with onboard EIDE Controller
  • 2 Intel PentiumPro 200 MHz 256 KB L2-Cache
  • 256 MB EDO RAM main memory (4*64MB SIMMs)
  • PCI 2MB graphic card
  • PCI Myrinet interface card M2M-PCI32B/512 KB
  • PCI FastEthernet (SMC 9332 BDT) with Netboot-PROM
  • 19"-industry PC case
  • 3.5" floppy disc drive
The entry module is additionaly equiped with the following
  • 2. PCI FastEthernet card
  • PCI SCSI-II controler
  • 12x EIDE-CDROM drive
  • 4 GB SCSI fixed disk
  • PS2 keyboard and mouse
The other modules are additionaly equiped with the following
  • NCR PCI SCSI-II Controler
  • 1 GB SCSI hard disk (from KSR)
The modules are located within a 19"-industry case.

2.1 Myrinet

Myrinet is a network technology developped by Myricom. It is based on point-to-point wires that links switches and final nodes to form any topology. Each link is capable of full bi-directional 1.2Gbit/s bandwidth.
